Tsawg- zaus kho qhov muag cable yog ib hom tshwj xeeb ntawm cable uas sib txuas fiber ntau-optic kis tau tus mob nrog cov yam ntxwv ntawm tsawg- zaus hluav taws xob cables. Piv nrog rau cov qauv qis- zaus hluav taws xob cables, qis- zaus kho qhov muag cables nthuav tawm qhov sib txawv tseem ceeb hauv qab no:
Transmission Medium
Tsawg- zaus hluav taws xob cables siv hlau conductors raws li lawv kis nruab nrab, whereas low-frequency optical cables siv optical fibers. Txij li cov fibers kho qhov muag muab kev sib kis ceev dua thiab ntau dua bandwidth, qis -frequency optical cables muaj qhov zoo sib xws ntawm kev sib kis.
Kev tiv thaiv kev cuam tshuam
Vim tias fiber ntau- kis tau tus mob optic tiv thaiv kev cuam tshuam rau electromagnetic cuam tshuam, qis-frequency optical cables outperform low- zaus hluav taws xob cables nyob rau hauv cov nqe lus ntawm kev cuam tshuam tsis kam. Cov cwj pwm no ua kom muaj kev ruaj ntseg zoo tshaj plaws rau kev qis - zaus kho qhov muag cables, tshwj xeeb tshaj yog nyob rau hauv complex electromagnetic ib puag ncig.
Tus nqi sib txawv
Txawm hais tias tsawg-frequency optical cables muaj qhov zoo hauv kev sib kis tau zoo, lawv cov nqi tsim khoom feem ntau yog siab dua li cov kab hluav taws xob tsawg- zaus. Yog li ntawd, nyob rau hauv kev siv tswv yim, kev xaiv ntawm cov cable uas tsim nyog yuav tsum tau coj los ntawm cov kev cai tshwj xeeb thiab kev txwv nyiaj txiag.
